You forgot the best part. Even though you have been given the jab you still can spread it to others who also have the jab( asymptomatic carriers). Apparently the Jab lowers your symptoms because it would have been really bad if you had not got the jab and got sick(How do they know? Total BS). So now you have people who are spreading it who are less likely to know they are sick. This also means the virus can live inside you and spread with the vaccine. I am not a scientist but that to me sounds like the perfect environment to mutate.
